A H 5 0 0 O p e r a t i o n Ma n u a l1 2 - 5 0Errorcode Description Remedy16#A0FCErrors occur in the slaves, onthe module of an AHRTU-DNETbackplane, or on theAHRTU-DNET backplaneconnection.1. Check whether the node number has changed.2. Check if the network connection cable is secured andworking fine.3. Check if the network transmission cable does notexceed the maximum communication distance (referto AH500 module manual section 11.3.3 for moreinformation). Do not exceed the maximumcommunication distance to ensure a stable network.4. Check if the module on the backplane is working fine.5. Check if the AHRTU-DNET backplane connection isworking fine.12.3.8 Troubleshooting for AH10PFBM-5AErrorcode Description Remedy16#A001 The master is not set. Download appropriate setting.16#A003 The master station enters thetest mode. Just repower it.16#A005A timeout occurs when chipsinside the master stationcommunicate.Download the appropriate configuration again. If the errorstill occurs, please contact the factory.16#A00BA timeout occurs whenAH10PFBM-5A exchanges dataexchange with a PLC.Repower AH10PFBM-5A . If the error still occurs, pleasecontact the factory.16#A402 The PLC does not assign theI/O mapping area to the master.Assign the appropriate I/O mapping area to the master viaISPSoft.16#A404 Master initializing error Contact the factory if the error still exists after repoweringAH10PFBM-5A.16#A406 Internal storage unit error Contact the factory if the error still exists after repoweringAH10PFBM-5A.16#A407 Data exchange unit error Contact the factory if the error still exists after repoweringAH10PFBM-5A.16#A408 Master serial number detectionerrorContact the factory if the error still exists after repoweringAH10PFBM-5A.16#A4E2 The master detects that theslave is offline.1. Check whether the PROFIBUS-DP bus connection isnormal.2. Check whether both of the ends of the network haveterminal resistors.16#A4E6The master detects that an erroroccurs in the module connectedto AHRTU-PFBS-5A.Check the modules connected to AHRTU-PFBS-5A.12.3.9 Troubleshooting for AH10PFBS-5AErrorcode Description Remedy16#A4F0The node address ofAH10PFBS-5A exceeds thevalid range.The node address of AH10PFBS-5A must be in the rangeof 1 to 125.16#A4F1 Internal hardware error If the error still exists after repowering AH10PFBS-5A,replace it with a new one.
